The aim of this study was to determine the effect of short-term consumption of omega-3 and vitamin E supplements on some indices of collagen breakdown (hydroxylysine and serum hydroxyproline) and muscle damage (lactate dehydrogenase, creatine kinase) in untrained young people.
Method: Eight healthy and non-active men (age: 21.33±2.12 years, fat percentage: 19.02±4.46) were selected using statistical methods to determine the sample size. Subjects were randomly divided into two conditions of supplement and placebo. The research design was carried out in a blind way and the subjects did not know about the content of the supplement packages until the end of the research protocol. At the time of taking supplements, they took 3000 mg of omega-3 supplement in three meals daily (1000 mg each) and 400 IU of vitamin E supplement in one meal. Soft gels containing oral paraffin were consumed as a placebo. On the eighth day, for both conditions of the research, the subjects had a bout of intense anaerobic activity, including 8 sets of 12 repetitions of pair jumping on the box and 8 sets of 12 repetitions of landing from the 43 cm box with a one-minute rest between each set. Before supplementing and 24 and 48 hours after performing anaerobic activity, blood samples tests were taken from the subjects.
Results: The results showed that the values of lactate dehydrogenase (p=0.033) and hydroxyproline (p=0.046) increased significantly in 48 hours after anaerobic exercise compared to baseline. No significant change was observed in the values of creatine kinase and hydroxylysine variables.
Conclusion: According to the findings, it seems that the combined consumption of omega-3 and vitamin E could not have a protective role on some indicators related to cell membrane and collagen damage, although more studies are needed for a more accurate conclusion.
